Don't miss your airport! Designed for pilots of any size aircraft, this app provides you with bearing and vertical speed required to nearby airports. The following information is shown for destinations:

• Distance from current location
• Field Elevation
• Descent rate required
• Time to Top of Descent (TOD)
• Bearing
• Frequencies
• Runways
• Glide distance delta

Additionally your current speed, course, altitude and vertical speed are displayed. Tapping on the information button, Time to TOD or Target Altitude allows you to customize the desired descent rate.

All data is updated in real time as you fly. You may choose a nearby airport or select an airport by identifier by scrolling down on the airport list. Filter by runway length and surface type and choose any of the following: airports, seaplane bases, heliports, balloon ports and closed airports.

You may optionally provide a glide ratio for your aircraft. The glide distance long or short of the selected airport is then displayed and is conveniently color coded. A positive, green glide delta indicates the glide distance has been estimated to exceed the distance to the airport with a 25% safety margin.

Runway headings, if known, are used to draw runways on the heading indicator. If the magenta arrow is pointed straight up and aligned with a runway then you are headed straight in.

Worldwide airport information is provided by multiple sources. Canada, Europe and all continents are covered! For more information go to Database updates are performed daily.

Your location and altitude is provided by your device's location services. If location or altitude is not available that information will not be displayed however you can still search for an airport by identifier. Unfortunately external GPS devices are generally NOT compatible.

You must be moving for course information and the magenta relative bearing arrow to be displayed.

The Watch app has many of the same features and fits on your wrist. See distances to nearby airports or bearing to a selected airport. Frequencies and runway lengths can be seen with a swipe. A green glide icon or delta indicates glideability is likely.

Just like the iPhone and iPad app, the Watch app requires GPS information to locate nearby airports and relative bearing. Additionally, altitude is needed to calculate descent rates. All watch versions are supported. Watch 1 requires an iPhone for GPS signal however a Watch 2 has it's own GPS.

Feedback and feature requests are appreciated. Thanks!

Great backup plan for your EFB

My CFI got me completely lost, even changed the heading indicator with the purpose of finding my way using the app, sure enough the app put me on top of the nearest airport.

I Love This App

I really like app much better than Xavion. Xavion has been tweaked to death and also wants $9.95 per month to keep it working.

Update after a year of use; I absolutely love this app. I have it running on a mini iPad mounted on the post between my windscreen and the pilot’s window. Both safety and convenience are enhanced by it use. As soon as I get close enough to my landing airport I will activate that airport and then go back to the "Nearest Airport" (Just in case). It will tell you the pattern altitude and also give you the time to start your decent at whatever decent rate you have programmed into it. It has never given any trouble at all and works well (mounted in that window) with only the iPad’s GPS. One of my more useful aviation apps. Update after over 100 hours airtime with this app; NRST has worked perfect and never given a minute of problems. I especially like the “TOD” feature that tells me when it’s time to start my decent. I normally fly from 6,000 to 9,000 feet and like not having to calculate my time to descend. I’ve noticed a couple of 1 Star ratings and do not have a clue as to why. Great aviation app.

Great app for situational awareness

Bought this app last week and did a cross country flight. Compared the reading to my Garmin 430W and were the same. Great app for situational awareness and gives TOD to the airports. I had a question and emailed the developer and was back to me very quick.

If you fly cross country and not familiar with all the location of the airports this is something you should have.
